Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it's a total body workout for your legs and abs, and works your heart and core unlike any other sport.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.

I think all tennis players have to struggle through the early stages of their career. We start off playing tournaments and really just get by. I always had a dream to play in the big tournaments and never have doubted if it was worth it. Having to battle a little early on in my career makes it all the more worthwhile now.

When I'm playing my best, like I was at the U.S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.

I think Serena Williams is the best tennis player of this generation, if not the best ever. It is amazing for her to be playing as well as she is at the age of 31.

I love to get home and hang out with my family. My brothers and I love spending time at the beach. I enjoy doing all kinds of surf sports and keeping healthy.
